I've bought the Z3 Compact, which, however, had in a warranty repair (can happen from time to time). I was for 2 weeks this HTC mobile phone as a transition. Now I can compare ...
!!! I'm not aware of on the surface, quality and appearance of a, because these points are very matter of taste. Also I value not the battery because the battery is always a special case and is not neutral evaluated by me in this review, but I'd say "holds" !!!
The HTC has simply a much slower processor and also significantly less RAM, this is clearly noticeable.
The small but subtle difference:
HTC also recognizes .flv videos, which are not recognized by Sony ... and makes no funny business when copying, with the message that this device, these files can not play ... BUT: MX Player makes this visible and playable ... at HTC they also appear in the gallery, only the jerk then clearly, so it makes no sense ... even with the MX Player ... (talking about 1080p at 30 frames).
Interim conclusion: HTC no complains and can not! Although Sony Z3 Compact bleats, but can anyway!
Display:
And now I understand what is not: Both displays have the same resolution. The promo video from Sony will be played sensationally detailed on the Z3C ... when HTC will also smashed .... lack of speed ??? Can not be both 720p displays and have it simply may pose great!
What is worth now because:
The Z3 Compact is much better ... It has Android 5 get, it's just a lot faster playing with MX Player (free in PlayStore available) everything smoothly from! Even takes on 4K videos and then can also play ...
Currently, the difference 50 ... which 3-fold pay off ... no longer buy HTC. Unless at 50 are the ghosts ... because it is a quite good phone.
Clear + for HTC: Loudspeakers. Which are significantly better than Sony, since HTC does not continue what before!
